Atomic Absorption Spectrometer Model (SGM-AA500 Series)

Features

Fully Automated

The flame and graphite furnace is integrated into one instrument. The change over from one technique to another is carried out by simple key strokes within the software. Instruments have a motorized 8 hollow cathode lamp turret which allows the automatic positioning and optimization of each hollow cathode lamp by the software.

The spectral bandwidth is automated and is available with choice of five slit sizes. Advanced Graphite Furnace.

Atomic Absorption Spectrometer Model (SGM-AA990 Series)

Features

Fully Automated

The flame and graphite furnace is integrated into one instrument. The change over from one technique to another is carried out by simple key strokes within the software.

The instruments have a motorized 8 hollow cathode lamp turret which allows the automatic positioning and optimization of each hollow cathode lamp by the software.

The control of the gas flows for the fuel gas (C2H2) and the positioning of the burner is also carried out directly from the software thus allowing optimization of the instruments for the best analytical parameter for a selected analysis.

Two methods of background correction are available. The first utilizes a deuterium lamp and the second is the proven method of self reversal.

The location of the wavelength and peak selection is automatic and controlled from the software. The spectral bandwidth is automated and is available with a choice of five slit sizes.

The electronic parameters for the photomultiplier detector, the hollow cathode lamp current and the balancing of the absorbance and background energies are controlled from the software.

The ignition of the flame is computer controlled and the various safety interlocks offer a very safe operating system.
